Ingredients
- Ghirardelli brownie mix: One box provides a rich and fudgy chocolate base that bakes evenly and delivers classic brownie flavor.
- Marshmallow cream (198 grams): Adds a fluffy, sweet layer with a silky texture that contrasts the dense brownies perfectly.
- Chocolate chips (340 grams): High-quality chips melt smoothly to mingle with peanut butter, forming a glossy, decadent topping.
- Smooth peanut butter (385 grams): Creamy peanut butter blends effortlessly with melted chocolate to add nutty richness and flavor.
- Rice Krispies cereal (150 grams): Provides a crispy crunch that gives exciting texture to the chocolate peanut butter layer.
Instructions
- Prepare and bake the brownie base
Preheat your oven and prepare the Ghirardelli brownie mix exactly according to the package directions. Baking ensures a fudgy, moist base that forms the foundation of the dessert. Allow the brownies to cool completely in the baking tin; this step is crucial to prevent the marshmallow layer from melting when applied.
- Spread marshmallow cream evenly
Once the brownies are cooled, gently spread the marshmallow cream across the entire surface using a spatula. The marshmallow acts as a sweet, airy layer that contrasts the dense brownie, adding a luscious texture to each bite.
- Melt chocolate chips carefully
Place chocolate chips in a heatproof bowl and microwave for 30 seconds initially, stirring to encourage even melting. Continue microwaving in short 10-second bursts, stirring after each, until fully melted and smooth—this gentle melting avoids burning and keeps the chocolate glossy.
- Combine peanut butter with melted chocolate
Add smooth peanut butter to the warm melted chocolate and stir until completely blended into a shiny, smooth mixture. This mixture will coat the Rice Krispies and form the crunchy topping layer.
- Coat Rice Krispies in chocolate peanut butter
Place Rice Krispies cereal into a large mixing bowl and pour the chocolate peanut butter mixture over them. Stir thoroughly so every piece is evenly coated, ensuring a consistent crunch and flavor in the topping.
- Assemble and chill
Evenly spread the coated Rice Krispies over the marshmallow layer on the brownies. Use a spatula to smooth the topping for a neat finish. Transfer the entire pan to the refrigerator and chill for at least 2 hours to allow the topping to set firmly, making slicing easier.
- Slice and serve
After chilling, remove from the refrigerator and slice into 12 squares. These brownies are best served cool to enjoy the perfect texture combination of fudgy, gooey, and crunchy layers.
- Ensure brownies are completely cool before adding marshmallow to prevent melting and sogginess.
- Use smooth peanut butter for a glossy finish; crunchy can be substituted for added texture.
- Keep brownies refrigerated after assembly to maintain topping firmness and freshness.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to 4 days to preserve freshness and texture. Allow brownies to come to room temperature for a few minutes before serving for best flavor.
Serving Suggestions
Pair these brownies with a cold glass of milk or a hot cup of coffee to complement the rich chocolate and peanut butter flavors. They also make a delightful sweet treat for potlucks or dessert buffets.
- Use high-quality chocolate chips for richer taste and better melting consistency.
